[Kanto] Tropical cyclone (Typhoon No. 8) approaches in the morning of the 27th (Saturday), and Typhoon No. 7 approaches in the evening, affecting transportation (commentary: Weather forecaster Atsuko Miyake)

2026/06/25 15:01

Heavy rain is likely to continue for a long time in the Kanto region from now until the 27th (Saturday) due to the rainy season front and two typhoons.
Please be aware that transportation may be affected.


The rainy season front is expected to remain near the Kanto region into tonight.
In addition, both typhoons No. 7 and No. 8 are expected to move northward from the southern sea. The extremely warm and humid air around the
typhoon flows into the front, increasing the activity of the
front.



First, let's look at the information on the approaching Typhoon No.8.
Typhoon No. 8 is expected to continue moving north without intensifying much.

It is expected to turn into a tropical cyclone off the coast of the Tokai region on the morning of the 27th (Saturday).

However, even if it turns into a tropical cyclone, very warm and humid air will flow towards the seasonal rain front that is stationary near the Kanto region, which will continue to stimulate the front.
Even after it becomes a tropical cyclone, it will bring heavy rain, so we cannot let our guard down.



Next, let's look at the information on Typhoon No.7.
After this, it is expected to approach Okinawa and Amami by tomorrow (Friday), accompanied by stormy winds.

After that, the storm area will disappear, but it is expected to quickly move across the Pacific side of western and eastern Japan.
It is expected to be closest to the Kanto region on the night of the 27th (Saturday).

However, this forecast may still change, so please continue to pay attention to the latest information.



Rain and wind forecast.
Let's take a look from midnight on the 27th (Saturday), when the rain and wind will be strongest in the Kanto region.

Rain is expected to fall widely in the Kanto region, and active rain clouds are expected to cover the Kanto region in the morning due to a tropical depression that will change from Typhoon No.8.

Shinkansen and expressways also run in the Tokai and Kanto regions, which are subject to active rain clouds.
Heavy rain and strong winds may affect transportation.



The rain will weaken temporarily in the afternoon, but then from evening to night, the rain clouds of
Typhoon No. 7 will approach. It looks like the rain and wind will become stronger again.

Rain clouds will move east towards the end of the night, but over the next three days, around 400mm of rain is expected to fall in most parts of the Kanto region.
It looks like it's going to rain quite a bit.
At this time of year, the amount of rain that falls in a month's worth is well in excess of the amount of rain that falls in one month, increasing the risk of heavy rain disasters.



Please be careful of landslides and river flooding.
If heavy rain falls in urban areas, there is a risk of large-scale flooding.
When it is raining heavily, please avoid going near underpasses.

In addition, transportation may be significantly affected on Saturdays and Sundays.
Please continue to pay attention to the latest traffic information.



, we will look at the detailed weather of each place.
It is expected that there will be heavy rain across the Kanto region until the 27th (Saturday).
Please continue to pay attention to the latest information.
And on the 28th (Sunday), the rain will stop in many places.
After that, the rainy season front will likely stay near Honshu, so
the weather will continue to be cloudy and rainy.

[Double typhoon + rainy season front] Be wary of heavy rain disasters due to long rain accumulation! (Commentary: Weather forecaster Atsuko Miyake)

2026/06/25 14:06

Heavy rain is expected to continue from now until the weekend as the rainy season front and two typhoons approach.
Please be careful of heavy rain disasters caused by long rain accumulation.



First, let's look at the amount of rain so far.
The rainy season front has been stationary and it has been raining for a long time.

The amount of rain is particularly high in Kyushu,
over the past 72 hours, more than 400 to 500 mm of rain has fallen in Nagasaki Prefecture.
All of these values have been updated to the highest in June, and this is record-breaking heavy rain.

A typhoon approaches where the ground has already become loose due to heavy rain.



Let's take a look at tonight's forecast weather map.
The rainy season front is expected to remain near Honshu into tonight.
The warm and humid air around Typhoon No.7 and No.8 will flow into the front, making the
front even more active.



Now, let's start with the information on the approaching Typhoon No.8.
Typhoon No. 8 is expected to move north without intensifying much.
The next day, on the morning of Saturday the 27th, it is expected to turn into a tropical cyclone off the coast of the Tokai Sea.



However, Typhoon No. 7 then approached as if chasing Typhoon No. 8.
Typhoon No. 7 is expected to approach Okinawa and Amami tomorrow, the 26th (Friday), accompanied by strong winds.

After that, the storm area will disappear, but on the 27th (Saturday)
it is expected to move east along the southern coast of Honshu while increasing speed.
It is expected to approach western and eastern Japan from the night of the 26th to the night of the 27th.



Rain is forecast from tonight.

Rain clouds associated with the rainy season front continue to rain widely across western and eastern Japan.
There is a risk of locally heavy to very heavy rain with thunderstorms.

Also, by the time the date changes to tomorrow (Friday) in the Okinawa region,
the rain clouds of the typhoon will begin to gather.

Very strong winds of over 30 meters will blow in the Okinawa region tomorrow,
There is a risk that strong winds could cause trucks to overturn.

There will be very strong winds and heavy rain, so tomorrow will be very stormy.



Tomorrow afternoon, a typhoon will approach the Amami region and the weather will be rough.

It is expected to continue raining in similar places around Honshu.
A low-pressure system accompanied by cold air is approaching near northern Japan, and there is a risk of rain and thunderstorms.



is forecasting rain clouds from the morning of Saturday the 27th.
Rain clouds associated with a tropical cyclone starting from Typhoon No. 8 are expected to cover the Tokai region.
The rain and wind are expected to intensify, potentially affecting transportation.

At noon, active rain clouds begin to gather in the Kanto region.
The rain stops in the Kanto region in the evening, but after that, rain clouds from Typhoon No. 7 begin to roll in.

At night, there is a risk of heavy rain and thunderstorms again in the Kanto region.
The wind will also become stronger.



After this, 300 to 400 mm of rain is expected to fall in many places until around the 27th (Saturday).
Please be wary of landslides, river surges, flooding, and flooding of low-lying areas.

In urban areas, when it rains heavily, please avoid going near underpasses.

Please be aware of the latest traffic information as transportation may be significantly affected on this Saturday and Sunday.



, we will look at the detailed weather of each place.

It will rain widely into the 27th (Saturday).
Please be careful of landslides caused by heavy rain in western Japan until tomorrow (Friday) and in eastern Japan until the 27th (Saturday).

Even in northern Japan, please be careful of sudden rain, lightning, and gusts of wind.
After the 28th (Sunday), the front will remain stationary near Honshu, and cloudy and rainy weather is likely to continue.

Typhoon No. 7 is expected to approach the Nansei Islands with strong winds until the 26th. After that, it will change its course to the east and increase its speed, and there is a possibility that it will approach the Pacific side of eastern Japan from western Japan on the 27th.

Typhoon No. 8 is expected to move northward over the sea south of Japan until the 27th, turning into a tropical cyclone off the coast of Tokaido.

Ferocious winds are expected to blow in the Okinawa and Amami regions on the 26th, which could lead to injuries from flying objects and the overturning of moving trucks. Please continue to take strict precautions against storms, such as refraining from going out unless necessary and staying away from windows when indoors.



Beware of heavy rain and landslides across a wide area of Honshu. Please be careful of landslides, flooding of low-lying areas, and river flooding, especially from the Pacific side of western Japan to eastern Japan until the 27th.



There is a possibility of severe gusts of wind such as lightning strikes and tornadoes, so if there are signs of a developed cumulonimbus cloud approaching, please try to stay safe by moving inside a building.
